Product History

Dungeon Master's Guide (1989), by David "Zeb" Cook with Steve Winter and Jon Pickens after Gary Gygax, is the second core rulebook for the AD&D 2e game. It was published in May 1989.

About the Title. Like the new Player's Handbook (1989) before it, the new Dungeon Master's Guide reclaimed its apostrophe. The punctuation has been a part of D&D titles ever since … except that the Dungeon Master's Guide temporarily became the Dungeon Master Guide in 1995, losing both its apostrophe and its "s"!.

It appears that the name of the Dungeon Master's Guide almost changed with the new release too. An article that Steve Winter wrote for Dragon magazine suggests that at one time this book was called the "Dungeon Master's Handbook", which would have created a parallel between the two core rulebook names. However, it was once more a Guide by the time it was published.

Moving Toward AD&D 2e. The second edition of Advanced Dungeons & Dragons was the product of two and a half years of work from editor Steve Winter and author David Cook. The Player's Handbook (1989) premiered in February and after that AD&D 2e game modules began to proliferate — including edition-changing adventures like WG8: Fate of Istus (1989) and the Avatar trilogy (1989). The Dungeon Master's Guide didn't appear until three months later, in May, but this was no great hardship for 2e players because most of the rules had already appeared in the Player's Handbook

Many Printings. The new Dungeon Master's Guide following the exact same pattern of production as the new Player's Handbook: it saw more than 10 printings over its first several years, then was revised as part of AD&D 2.5e (1995), and more recently was published yet again by Wizards of the Coast (2013) in a premium edition.

A Different Sort of Dungeon Master's Guide. The original Dungeon Masters Guide (1979) was the core rulebook for AD&D first edition. But now, the Player's Handbook had become the core rulebook for the second edition game. So, for the first time ever, TSR had to ask itself: what should really go in a book for the Dungeon Master?

Like the first edition Dungeon Masters Guide, this new book's structure parallels the organization of its Player's Handbook: character abilities are followed by races, then classes, then alignment, just like in the Player's Handbook. However, one of Steve Winter's major goals for the 2e releases was that there be no repeat of material between the books. Thus the Dungeon Master's Guide instead acts as a commentary and addendum to the Player's Handbook. It's filled with basic GMing advice and additional background on the various topics; it also contains yet more optional rules, including rules for creating new races and classes. These toolkit rules aren't the sort of thing found in more recent Dungeon Master's Guides, but they show off one of Zeb Cook's major goals for 2e: that the new rules be guidelines that players could adjust for themselves.

Magic items are the one truly core mechanic found in the Dungeon Master's Guide — a division that D&D has maintained through every edition of D&D except 4e (2008). Artifacts can also be found, though with the lowest count ever. The scant three artifacts of 2e can be considered a list of D&D's most interesting: the Hand of Vecna, the Rod of Seven Parts, and (somewhat more mysteriously) Heward's Mystical Organ. Second edition would correct its artifact deficiency several years later with the Book of Artifacts (1993), also by Cook.

What a Difference an Edition Makes. Most of the rules changes for AD&D 2e had already appeared in the Player's Handbook, but there was one surprising take back: assassins reappear, not as a character class, but as a "reprehensible mind-set". Though assassins are usually included in lists of the bowdlerized elements in AD&D 2e, their slight inclusion here supports Cook's later statement that he removed them only because they were bad for party unity.

Many Appendices. The original Dungeon Masters Guide was filled with well-loved appendices, including many wacky encounter tables and the famous list of inspirational reading. Steve Winter's article about second edition AD&D in Dragon #126 (October 1987) confirmed that there would be an appendix of "useful tables", but it turns out to be all treasures and magic items.

It was perhaps an understandable change. The many and varied appendices of the first Dungeon Masters Guide were a product of its chaotic creation as a stream-of-consciousness compendium. The second Guide was a wholly different thing, created in a different era of publication.

Expanding the Outer Planes. Though demons and devils were left on the cutting room floor of AD&D 2e due to fear of "angry mothers", TSR hadn't yet cut up the Outer Planes as well. A short discussion of them references their classic names — including the Nine Hells, the Seven Heavens, and the Twin Paradises. These planes would be rebooted in Planescape (1994), then their new names would be tipped into the 2.5e version of the Dungeon Master's Guide (1995).

About the Creators. Cook was the designer for the AD&D 2e project, working alongside editor Steve Winter, who set many of the original organizational goals.

I love 2nd Edition AD&D, so there is nothing wrong with the substance of the book. However, I really hate the revised edition. The art, layout, drab colors with glaring red titles and boxes, and general asthetics of the book don't compare at all [...]

This is obviously a very important book to have if you are into AD and D. Lots of good information and I was pretty happy with the scan and bookmarks. I definitely recommend this one!<br><br>

I think the DMG 2nd Edition revised is a good book and I don't see to much difference from the unrevised version and to get it in a pdf format I think is awsome. Thanks rpgnow.com<br><br>

These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.

Original electronic format

These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
